so basically I've gotten the chance to build a computer that has a budget of $2,000 to $3,000. But I just don't know anything about computers. See I'm in dire need for an upgrade from my current MacBook Pro, and this is because I work using the 3D Animation program known as Blender. I need a PC that renders animations in Blender extremely fast, both Cycles and Internal. I also want to use this computer for gaming. I won't keep too many games on it, I for the most part want to just run Dolphin Emulator on it and maybe a few other PC games, but I need to know what I need in order to build this computer that would be within my budget. I don't know anything, nothing about CPU, GPU, nothing. I want to get a high quality monitor, 4K or higher, a good keyboard which I can probably choose on my own, and uh yeah that's pretty much it. Here are the specs for my recent MacBook Pro:
Processor - 2.3 GHz Intel Core i7
Memory - 16 GB 1600 MHz DDR3
Graphics - NVIDIA GeForce GT 750M 2048 MB Intel Iris Pro 1536 MB
So my sister got her computer built and i want to follow the same steps she did which was getting all the information and then buying the parts needed, and then going to Fries Electronic so I can get it built. Again, not sure about what all that info is and I don't know if this is possible but I heard that you can have multiple graphic cards in the computer for very good improvement, if anyone can explain to me what I need (but act like you're talking to a 5 year old) then I'd be all set. Anyways, thanks!
Additional Info: Parts don't need to be available right now, things can wait a few weeks / months.
